[edit] Walkthrough

Mountain Dwarf.Go to the tunnel under White Wolf Mountain that you unlocked in the Fishing Contest. You will see an old dwarf, Rohak, in the bar area. Talk to him. He will refuse to bake a Dwarven rock cake for you, but he'll mention the Rising Sun Inn. Go to Falador and talk to Emily in the Rising Sun Inn next to the west bank. Ask her about 'dwarves and ale'. she will offer to tell you the secret recipe for Asgoldian ale for the price of 200 coins. If you have the activated Ring of Charos, charm her. She will tell you to add a gold coin to an Asgarnian ale to get an Asgoldian ale. Buy four Asgarnian ales from her, then add coins as per the secret recipe. Once you have four go back to the tunnel under White Wolf Mountains and give them to Rohak. He will not tell if you don't give him all the Asgoldian ales at once; you'll know you've done it right when there's a brief fade-out accompanied by the statement, "Several beers later..." He will agree to make you a rock cake. Give him 100 coins, then your bucket of milk, egg, flour, and bowl of water then wear your gloves. You will need to cool it down before you can give it to the Dwarf back in Lumbridge. Pick it up while wearing any gloves, you need to be quick, it'll disappear very quickly. The cake will still be very hot.
Ways to cool the Rock cake:
If you have ice gloves, you can give the cake to the dwarf immediately.
If you are wearing normal gloves you will need to let the cake cool down in your bank for about a day
Or you can go to Ice Mountain and kill an ice fiend.
Give the cooled cake to the Dwarf to complete this subquest.
